【求助】关于matlab里不能实数阵卷积的问题及函数信号发生器问题
 

安装的是2006b，其实开始2006a也是试过。
问题很奇怪
就是conv函数不能用在实矩阵下
a=[2 3];
b=[3 4];
conv(a,b);再回车就有问题了（为不致太乱错误提示下面我回帖提供）
但是若a=[2+1i 3+2i]就没问题了，只要有复数就可以
很奇怪，在另外一台机子上使用是正常的，安装的是一样的版本。
************
还有就是刚才说的另一台机子上的问题了
也就是函数发生器，matlab指令是daqfcngen
在那机子上不能用，一回车就出问题，而在我那不能实矩阵卷积的机子上却能正常运行，真的是很奇怪的是，安装的都是一样的啊。
************
请各位大虾帮忙啊~~~~
谢过先了~~~~
问题补充：对了
对于conv.m和filter.m函数文件我是看过的
跟可以运行的机子上是一样的
还有就是我的matlab在启动是总是弹出“找不到指定模块”的警告框，先前装的2006a也是这样，难道和我的系统有关么？？

****************
下面是错误提示：

先是弹出一个“找不到指定程序”的警告框
然后在commond window 里是：
